Wondering how to check your iPhone battery health? Think you might need to replace your iPhone battery?
If you’ve had your phone for a couple of years, then your battery could be starting to degrade. This quick guide will show you how to find out if your iPhone needs a battery replacement.
1. Apple Support
You can either take your iPhone to the nearest Apple Store or have them check it remotely. This is probably the easiest and the most reliable way to check your battery’s health.
Either way, they’ll run the diagnostic test, and let you know whether your battery passes the test.
2. Battery Settings
There’s another way provided by Apple to figure out how your iPhone battery is doing. iOS 11.3 and newer versions bring a new Battery Health tool that lets you monitor the health of your battery.
- Open the Settings app on your iPhone
- Choose Battery
- Tap on Battery Health
- The Battery Health screen will show you two important indicators of battery health: Maximum Capacity and Peak Performance Capability
The Maximum Capacity means how in good health your battery is. All new iPhone and new iPhone batteries will have a maximum capacity of 100%.
As time goes by, the battery will take a beating and degrade, so its maximum capacity may reduce below 100%.
As you can see in the picture above, the maximum capacity of this iPhone’s battery is at 84%, which is still in good shape.
Here’s what Apple has to say about maximum capacity battery:
Maximum battery capacity measures the device battery capacity relative to when it was new. Batteries will start at 100% when first activated and will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges.
A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions. The one-year warranty includes service coverage for a defective battery. If it is out of warranty, Apple offers battery service for a charge.
The Peak Performance Capability section will let you know if anything is wrong with your iPhone’s battery.
For batteries in good shape, you may see “Your battery is currently supporting normal peak performance.”
If there’s any issue, you’ll probably see “Your battery health is significantly degraded. An Apple Authorized Service Provider can replace the battery to restore full performance and capacity.”
3. Coconut Battery
With Coconut Battery, you’ll get full details about your iPhone battery’s health. Keep in mind, it’s a third-party app, and it’s not available at the App Store. So, consider downloading it at your own risk.
After you download it, connect your iPhone to your Mac and launch the App. Head over the iOS Device tab, you should be able to see some important details about your battery’s health.
According to Apple, a battery is in good condition, if it has 80 percent or more left of its capacity at 500 complete cycle counts.
To put that into context, the iPhone 6S Plus battery in the above picture on the left-hand side needs to be replaced. It has less than 80 percent at 650 complete charge counts.
Coconut Battery only gives you accurate information if you haven’t restored your iPhone. So, keep this in mind.
Another great alternative is an App called Lirum Device Info, which you can download from the App Store.
This app not only gives you the details about your iPhone battery health but also about all the components that make your iPhone. It’s totally worth a spot on your iPhone.
4. Console App
Last but not least, you can check your iPhone battery’s health through the Console Application pre-installed on your Mac.
Just go ahead connect your iPhone to your Mac, then go over Applications > Utilities and launch Console App. To do that your iPhone needs to be unlocked and trusted by that Mac.
Once the App has launched, under the “Devices” tab in the left-hand sidebar choose your iPhone, and type BatteryHealth in the search field.
You’ll find all the details on your iPhone battery health. As you can see, my iPhone X battery is in good condition.
